What is the significance of zitterbewegung in quantum mechanics and how does it affect the behavior of particles?

Zitterbewegung is a rapid trembling motion exhibited by particles in quantum mechanics. It is significant because it highlights the inherent uncertainty and dual nature of particles as both waves and particles. This motion affects the behavior of particles by causing fluctuations in their position and momentum, leading to unpredictable movements and contributing to the probabilistic nature of quantum mechanics.
